Fluorine-containing pesticide intermediates    In the search for ways to improve biological activity, fluorine is often used in place of hydrogen or chlorine. This substitution can greatly improve the efficacy of pesticides, and the introduction of fluorine atoms into the structure of pyrethroids increases the efficacy against pests and has an acaricidal effect, so fluorinated pyrethroids have been of interest. However, it is necessary to select the fluorine substituent position of the molecule to prepare the most active compounds. Fluorine atom insertion plays a key role in biological activity, but fluorine substitution of hydrogen often reduces the activity, however, the most active compounds often contain fluorine atoms in some positions of the molecular structure, and to prepare fluorine-containing compounds with high activity, fluorine-containing intermediates are necessary, so research and development of fluorine-containing intermediates become very necessary.,Disclaimer: The above content is for reference and communication only among industry insiders, and does not guarantee its accuracy or completeness.
